# HTML5 - MathML

The HTML syntax of HTML5 allows for MathML elements to be used inside a document using [itex]...[/itex] tags.

Most of the web browsers can display MathML tags. If your browser does not support MathML, then I would suggest you to use latest version of Firefox.

## MathML Examples

Following is a valid HTML5 document with MathML −

```<!doctype html>
<html>

<meta charset="UTF-8">
<title>Pythagorean theorem</title>

<body>

<math xmlns="http://www.w3.org/1998/Math/MathML">

<mrow>
<msup><mi>a</mi><mn>2</mn></msup>
<mo>+</mo>

<msup><mi>b</mi><mn>2</mn></msup>
<mo>=</mo>

<msup><mi>c</mi><mn>2</mn></msup>
</mrow>

[/itex]

</body>
</html>
```

This will produce following result −

## Using MathML Characters

Consider, following is the markup which makes use of the characters &InvisibleTimes; −

```<!doctype html>
<html>

<meta charset="UTF-8">
<title>MathML Examples</title>

<body>

<math xmlns="http://www.w3.org/1998/Math/MathML">

<mrow>
<mrow>

<msup>
<mi>x</mi>
<mn>2</mn>
</msup>

<mo>+</mo>

<mrow>
<mn>4</mn>
<mo>⁢</mo>
<mi>x</mi>
</mrow>

<mo>+</mo>
<mn>4</mn>

</mrow>

<mo>=</mo>
<mn>0</mn>

</mrow>
[/itex]

</body>
</html>
```

This would produce following result. If you are not able to see proper result like x2 + 4x + 4 = 0, then use Firefox 3.5 or higher version.

This will produce following result −

## Matrix Presentation Examples

Consider the following example which would be used to represent a simple 2x2 matrix −

```<!doctype html>
<html>

<meta charset="UTF-8">
<title>MathML Examples</title>

<body>
<math xmlns="http://www.w3.org/1998/Math/MathML">

<mrow>
<mi>A</mi>
<mo>=</mo>

<mfenced open="[" close="]">

<mtable>
<mtr>
<mtd><mi>x</mi></mtd>
<mtd><mi>y</mi></mtd>
</mtr>

<mtr>
<mtd><mi>z</mi></mtd>
<mtd><mi>w</mi></mtd>
</mtr>
</mtable>

</mfenced>
</mrow>
[/itex]

</body>
</html>
```

This will produce following result −

This would produce following result. If you are not able to see proper result, then use Fire fox 3.5 or higher version.
